Overview of the development of aluminum alloy wheels
In various measures to achieve lightweight automobiles, the focus is on the walking system. For this reason, trying to use light metal materials (aluminum, magnesium and organic materials (polymer materials) in the system of walking system has become the general trend of the development of aluminum alloy reduction wheels. In various measures to realize the lightweight car, the focus is For this reason, trying to use light metal materials (aluminum, magnesium and organic materials (polymer materials) in the system of walking system has become the general trend of the development of aluminum alloy reduction wheels. System. Therefore, the use of light metal materials (aluminum, magnesium, and organic materials (polymer materials) in the walking system is an effective measure. Some data show that the effect of reducing the quality of the wheels is far greater than the weight to reduce other automotive parts, and and the weight of other automotive parts, and and the weight of other automotive parts, and the weight of other automotive parts, and the weight of other automotive parts, and the weight of other automotive parts, and the weight of other automotive parts, and the weight of other automotive parts, and the weight of other automotive parts, and the weight of other automotive parts, and the weight of other automotive parts, and the weight of other automotive parts, and the weight of other car parts, The test shows that the wheels (wheels and wheel spokes) have the potential to reduce weight on the basis of meeting their performance requirements. Therefore, although car light metal materials are still mainly used for the body, the amount of use in rotating parts and vibration parts increases day by day. The quality of the wheels is first, and in 1997, the market share of the aluminum wheels was about 50%.
The aluminum wheels have been used for 20 years, which has an impact on the car. In 1923, the aluminum wheels of the sand casting process were installed on the car made by Pajaki. Since then, Germany Benz has developed a spoke-type aluminum wheel with riveting aluminum wheels in three years, using rims to squeeze and forming. This aluminum wheels are only used for racing. After World War II, aluminum alloy wheels were used for ordinary cars. In 1958, there was an overall-cast aluminum wheel, and the forged aluminum wheels soon. In 1979, the United States used the aluminum-shaped wheels as a standard wheel. In 1980, the world’s first semi-solid mold forging (SSF) aluminum alloy wheel factory was put into production in Fiyateville, Akenusta. Entering a new stage. In 1981, the United States Kaize Aluminum Chemical Company produced an overall wheel of aluminum alloy cars with a squeezing method for the first time, with a diameter of 457.2 mm. In the mid-1980s, it was used for small cars equipped with front-wheel drive.
According to information, the United States, known as the “country on the wheel”, has an average car consumption of car in 1985 to 4.5%, and 7.3%in 1990; Germany is expected to reach 8%of the total by 2000. A considerable part (about 2%) is used to manufacture wheels. In 1989, a German magazine reported that 7%of Federal Germany and more than 18%of the United States were equipped with high-strength aluminum alloy wheels. It is also reported that the output of Japanese steel wheels is generally stable, while aluminum wheels have grown rapidly. In 1973, the “Light Metal Wheel Committee” was established. In the same year, the aluminum wheels for automobiles began to produce in batches. In 1977, the aluminum wheels of trucks and bus began to produce in batches. In 1979, the aluminum wheels of motorcycles began to produce in batches. During the four years from 1976 to 1981, the output of aluminum wheels increased by 20 times. With the improvement of the installation and popularization of A.B.S (anti-hugging braking device), the use of aluminum alloy wheels has accelerated. At present, the installation and popularization rate of aluminum alloy wheels abroad is 30%, and it is expected to reach more than 50%in the future.
